"Lord, we pray that you would give (the girl's family) supernatural strength," Pastor Monique McCord said at Jonylah Watkins' funeral with hundreds in attendance at a church in the Woodlawn neighborhood where the shooting occurred.
The girl's father, 29-year-old Jonathan Watkins, was seriously wounded in the March 11 shooting. Watkins wore a white hooded sweatshirt and bowed his head over the small casket on Tuesday for about 10 minutes. He had nicknamed his daughter Smooch.
The baby's grandmother, Mary Young, read a poem at the funeral and several religious leaders spoke.
"All of us need to apologize to her for not doing our best to make the world a better place," Pastor Marshall Hatch said. "She deserved better."
Earlier Tuesday mourners filed past the baby's open casket. On Monday a line formed outside a funeral home as members of the public offered condolences to the family. A local funeral home is paying for the services.
Chicago Police Superintendent Garry McCarthy said Monday investigators will solve the baby's murder.
